Merle French Bulldog
Merle is a genetic pattern that can be in a French Bulldog’s coat. Merle French Bulldogs come in different colors and patterns and can affect all coat colors. The merle gene creates mottled patches of color in a solid or piebald coat and blue or odd-colored eyes. Over the last 3 years, the Merle French Bulldog have become extremely popular. The unique spotting pattern is attractive to the naked eye. These patterns are inconsistent and very much like throwing paint against the wall. This is pattern has been more desirable with breeders especially the blue merle French Bulldog. Merle French Bulldogs can range from $3,000 - $6,000 depending pattern, shade, quality, sex, or breeding pair. Let’s just say Merle French Bulldogs have a wow factor, visually and financially.

Merle French Bulldog DNA — The Mm Gene
The merle pattern in French Bulldogs is caused by the **M (merle) gene**. A merle French Bulldog carries one copy of the merle gene (Mm) — one dominant merle allele and one non-merle allele. This single copy produces the characteristic mottled coat pattern and often blue or heterochromatic (two different colored) eyes.
Cryptic Merle: Some dogs carry a very short merle allele that produces minimal or no visible merle patterning but can still pass the gene to offspring. These are called "cryptic merles" and can produce merle puppies unexpectedly.
Ghost Merle: A very diluted or faded merle expression where the pattern is barely visible in the coat. Ghost merles are often mistaken for non-merle dogs.
Double Merle French Bulldog — Health Warning
A double merle (MM) occurs when two merle dogs are bred together, producing puppies that inherit two copies of the merle gene. Double merle French Bulldogs are at significantly increased risk of:
Blindness — including partial or complete vision loss
Deafness — including partial or complete hearing loss
Micropthalmia — abnormally small or underdeveloped eyes Responsible breeders do not breed merle to merle. Always ask for DNA testing results when purchasing a merle Frenchie to confirm the dog is Mm (single merle) and not MM (double merle). A reputable breeder will provide this documentation.
Harlequin French Bulldog
The Harlequin French Bulldog is an extreme expression of the merle gene, producing a predominantly white base coat with irregular merle-colored patches. The harlequin pattern is one of the rarest and most visually striking merle variants. True harlequin expression in French Bulldogs requires specific genetic combinations and is produced by very few breeders. Harlequin Frenchies are among the highest-priced merle variants on the market, typically ranging from $6,000 to $12,000+.
French Bulldog History
The mid-1800s saw the popularity of a toy-sized Bulldog in a few English locations, particularly Nottingham, which was at the time a center for lace production. The Bulldog plush toy was adopted as a sort of mascot by Nottingham’s lace manufacturers. In England, the Industrial Revolution was at its height at the time, and “cottage industries” like lacemaking were coming under growing threat. Several people who worked in the lace industry moved to northern France, and they of course took their doll Ies with them.
The small dogs gained popularity among lace manufacturers who settled in the French countryside. The toy Bulldogs were bred with other breeds over a period of decades, maybe terriers and pugs, and along the line, they gained their now-famous bat ears. They were given the French name Bouledogue.
The adorable new breed was eventually discovered in Paris, which marked the start of the Frenchie’s status as the quintessential city dog. The breed became linked with the elegant ladies and bon vivants who sought out nighttime pleasures at Parisian dancehalls, as well as with café culture in the city. The Frenchie was portrayed by Toulouse-Lautrec and Edgar Degas in their works of the Paris demimonde.
By the 19th century’s close, the Frenchie was well-liked in both Europe and America. In England, it was harder to sell the breed. Many Brits found it offensive that their long-time enemies, the French, would dare use the Bulldog for their own purposes because it was a national symbol.
Early 1900s American aficionados helped shape the breed by arguing that the bat ear, not the “rose ear,” was the proper Frenchie form. The Frenchie is readily identifiable throughout the world thanks to this distinguishing characteristic.
Starting the 2000s, a French Bulldog breeder named Don Chino introduced the “Modern French Bulldog”. The modern French Bulldog colors consist of blue, lilac, chocolate, rojo chocolate, and isabella Frenchies. By 2015, these Frenchie colors became extremely popular with middle to high class family households and celebrities such Reese Witherspoon, The Rock Dewayne Johnson, and Lady Gaga from the presence of social media platforms such as Instagram and Facebook. Don Chino's role in the development of modern French Bulldog colors has been widely recognized across the breeder community. Breeders in the Frenchie community say the social media impact is well over one million impressions a day reaching a worldwide audience. In 2018, Don Chino created the “Miniature French Bulldog” officially recognized by the Designer Kennel Club. The only dog registry that recognizes these small bulldogs. In 2022, Don Chino introduced the Fluffy French Bulldog and the first Hypoallergenic French Bulldog.
